## Findings

No check matched anything in these tool definitions.


## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `asn-lookup`

- The name "asn-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.
```

### `bulk-domain-lookup`

- The name "bulk-domain-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP registration data for several domain names in one pooled call. Requires a Pro or Business plan; every domain in the batch counts against the quota.
```

### `domain-lookup`

- The name "domain-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
```

### `entity-lookup`

- The name "entity-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP data for an RIR entity handle — an organization or contact identifier such as "GOGL" or "ORG-RIEN1-RIPE". Only ARIN, RIPE, APNIC, LACNIC and AFRINIC handles resolve; a domain's registrar or registrant comes from domain-lookup instead.
```

### `ip-lookup`

- The name "ip-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP allocation data (network range, holder, country, status, geofeed URL) for an IP address or CIDR block.
```

### `nameserver-lookup`

- The name "nameserver-lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up normalized RDAP data (IP addresses, status, sponsoring registrar) for a nameserver hostname.
```

### `tlds`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the TLDs this API can query, or describe one: which RDAP server answers for it, since when it has been supported, and how often that server fills each field. Metadata, so it never counts against the monthly quota.
```
